Stricter gun laws associated with decreased in-home pediatric firearm homicides



These incidents were often associated with child abuse and intimate partner violence, according to new research




American Academy of Pediatrics





DENVER — States that have adopted stronger gun control legislation experience lower rates of in-home pediatric firearm homicides, according to research presented during the American Academy of Pediatrics 2025 National Conference & Exhibition at the Colorado Convention Center Sept. 26-30.

The research, “Killed in Their Own Homes: The Rise of Pediatric Firearm In-Home Homicides and Association with State Firearm Laws,” examined data from the National Violent Death Reporting System and U.S. Census Bureau from 2005 to 2021, focusing on pediatric in-home firearm homicides. The pool was then narrowed to only include the 14 states with consistent data covering the entirety of the study.

Researchers found that during the years examined, there were 3,289 firearm-related homicides across 14 states, including 2,633 (80.0%) among teenagers ages 13-17 years and 656 (20.0%) among children ages 12 and younger. The numbers represent a rate of in-home firearm-related homicide ranging from 0.18 homicides per 100,000 children and adolescents in 2010 (the lowest rate observed in the 17-year timeframe) to 0.48 homicides per 100,000 in 2020. These homicides were often reported alongside incidents of child abuse and intimate partner violence.

Researchers examined which of the 14 states had the strongest gun control laws. They found that extreme risk protection order laws, often called red flag laws where family members or law enforcement can petition the court to remove firearms from the home of someone they believe to be at risk, were in place in five of the seven states with the lowest rates of in-home homicide. By contrast, only two of seven states with the highest rates of in-home homicide had such laws.

Authors state that federal gun control laws may not be sufficient to curtail these incidents and suggest   strengthening laws at the state level.

"Given evidence that stronger state firearm laws are associated with fewer pediatric in-home homicides, future advocacy should seek to expand gun laws, including extreme risk protection orders which may prevent these cases by removing firearms from high-risk households,” said research author Jordan Rook, MD.

The authors conducted research through the American Pediatric Surgical Association and American Academy of Pediatrics Advocacy Committee.

Dr. Jordan Rook is scheduled to present the research, which is below, from 8:50 a.m. to 8:57 a.m. MDT on Friday, Sept. 26 at the Colorado Convention Center, Bluebird Ballroom 2A. To request an interview with the authors, contact Jordan Rook at jrook@mednet.ucla.edu.

In addition, Dr. Rook will be among highlighted abstract authors who will give a brief presentation and be available for interviews during a press conference from noon-1:30 p.m. MDT Saturday, Sept. 27, in the National Conference Press Room, CCC 705/707.

Abstract Title: Killed in Their Own Homes: The Rise of Pediatric Firearm In-Home Homicides and Association with State Firearm Laws

Jordan Rook

Los Angeles, CA, United States

Firearm-related injury is the leading cause of death for children and adolescents in the United States, with most deaths due to homicide. Prior research has demonstrated that one-quarter of child and adolescent homicides occur at home. Despite representing a major setting for pediatric mortality, it remains unknown how firearm laws, which vary widely across states, may affect rates of in-home pediatric homicide.

We used the 2005-2021 National Violent Death Reporting System and US Census data to conduct a repeated cross-sectional analysis of child and adolescent victims (0-17 years) of firearm-related homicide. We restricted analyses to 14 states that contributed continuously to NVDRS over this 17-year period. We assessed the state-based incidence of firearm-related homicide and firearm-related in-home homicide. We evaluated temporal trends with linear regression. We evaluated the association of in-home firearm-related homicide rates with the strength of state firearm laws as determined by the Giffords Law Center Gun Law Scorecard using Spearman’s Rank Correlation coefficient (ρ).

From 2005-2021, there were 3,289 firearm-related homicides across 14 states, including 2,633 (80.0%) among teenagers aged 13-17 years and 656 (20.0%) among children aged 12 and younger. Of these, 27.5% (n=905) occurred at home including 17.4% (n=459) of teenage homicides and 68.0% (n=446) of child homicides. In-home homicides were more often associated with child abuse (11.2% [n=101] vs 1.2% [n=29]; p< 0.001) and intimate partner violence (20.8% [n=188] vs 4.3% [n=103]; p< 0.001). From 2005-2021, the incidence of firearm-related homicide ranged from 0.69 homicides per 100,000 children and adolescents in 2013 to 1.82 homicides per 100,000 in 2021 (β=0.03; 95%CI -0.001-0.06; p=0.06). The incidence of in-home homicide ranged from 0.18 homicides per 100,000 in 2010 to 0.48 homicides per 100,000 in 2020 (β=0.01; 95%CI=0.01-0.01; p=0.02; Figure). The incidence of firearm-related in-home homicide was lowest in Massachusetts (< 0.10 deaths/100,000 children and adolescents) and highest in South Carolina (0.49 deaths/100,000). Increased strength of state firearm laws was correlated with lower rates of in-home firearm-related homicide (ρ=0.72; p=0.004). Extreme Risk laws have been passed in five of the seven states with the lowest rates of in-home homicide versus two of seven states with the highest rates of in-home homicide.

Over a quarter of firearm-related homicides among children and adolescents occurred at home, with rates of in-home homicide increasing during the study period. In-home homicides comprised over two-thirds of total homicides among children aged 12 and younger. Federal firearm laws may inadequately address the factors that precipitate these incidents like intimate partner violence and child abuse. With evidence that stronger state firearm laws are associated with fewer pediatric in-home homicides, future advocacy should seek to expand gun laws including extreme risk protection orders which may prevent these cases by removing firearms from high-risk households.

 

Medicaid billed for 52% of U.S. hospital costs from gun injuries



Gun-injury care cost U.S. hospitals $7.7 billion from 2016 to 2021, with Medicaid covering 52% of costs

Medicaid reimbursement often falls short of actual treatment costs, leaving trauma centers on the front lines of the gun violence epidemic to absorb substantial losses

Study authors concerned Medicaid funding cuts could further strain trauma centers

Costs stayed flat through 2019, then rose 33% from 2019 to 2021, coinciding with a rise in firearm injury during the pandemic


CHICAGO --- The initial hospital treatment of firearm injuries cost the U.S. health care system an estimated $7.7 billion between 2016 and 2021, with the largest share falling on urban trauma center hospitals that serve the highest proportion of Medicaid patients, reports a new study led by Northwestern Medicine.

The study analyzed emergency department and inpatient visits for firearm injuries between 2016 and 2021. Annual costs held steady at about $1.2 billion through 2019, then jumped to $1.6 billion in 2021, a 33% increase that coincided with a rise in firearm injuries during the COVID-19 pandemic.

More than half of all firearm injury costs were billed to Medicaid. Yet, Medicaid reimbursement often falls short of actual treatment costs, leaving safety-net hospitals, which serve vulnerable, lower-income patient populations, on the front lines of the gun violence epidemic to absorb substantial losses. The study authors warn that recent Medicaid funding cuts adopted by Congress could further strain these hospitals.

The findings will be published on Friday (Sept. 26) in JAMA Health Forum.

“Gun injuries are a source of financial strain on hospitals, particularly large safety-net trauma center hospitals that often operate on thin margins,” said study corresponding author Alexander Lundberg, assistant professor of emergency medicine at Northwestern University Feinberg School of Medicine.

“Because in many states Medicaid reimbursement is typically below the true cost of care, trauma center hospitals are already absorbing significant losses,” added study co-author Dr. Anne Stey, assistant professor of surgery at Northwestern University Feinberg School of Medicine and a Northwestern Medicine trauma surgeon.

“Medicaid funding cuts could further financially destabilize trauma centers. Some could close, or stop being trauma centers that provide the high-level and life-saving trauma care that all American families need after car accidents, falls and bike accidents.”

Overall, the largest share of costs went toward treating patients who were Black, men and from low-income areas.

How the study was conducted

To get a national picture of the health care costs of firearm injuries, the scientists analyzed hospital records from six states: Arkansas, Florida, Maryland, Massachusetts, New York and Wisconsin. The team chose these states because they collect high-quality data on both inpatient hospitalizations and emergency visits.

The team analyzed every hospital visit in those states for a new firearm injury from 2016 to 2021 and then used these patterns to generate national estimates.
To find out where in the health system the costs are most concentrated, the team broke down the data by patient demographics, hospital size and health insurance coverage, among other factors.

Key findings

  • The initial treatment of firearm injuries cost U.S. hospitals $7.7 billion from 2016 to 2021
  • Annual costs stayed stable from 2016 to 2019 (about $1.2 billion per year) before climbing to $1.6 billion in 2021
  • The annual cost of treatment for pediatric patients grew 54% from 2019 to 2021
  • Medicaid was the primary payer for 52% of all hospital costs, followed by private insurance (20%), self-pay or uninsured patients (16%) and Medicare (6%)

Beyond the hospital bill
The Northwestern team notes that their estimate likely understates the complete financial toll of firearm injuries. Their analysis included only the initial hospital stay or emergency visit and did not capture other significant health care costs related to firearm injuries, such as ambulance or air transport, rehabilitation, follow-up visits and return to hospital.

The study also does not account for indirect costs to American families such as lost wages of patients and their caregivers, long-term disability or the emotional and economic burden on communities.

Solutions

Lundberg and colleagues say their findings highlight the need to strengthen financial support for trauma center hospitals to sustain trauma care in their communities most affected by gun violence.
The authors also call for more investment in injury-prevention programs and safe-firearm storage education to prevent unauthorized firearm access.

The study is called “Health Care Costs of Firearm Injury Hospital Visits in the US.”
